The plywood should be fine and get a nice smooth edge. Your joiner might suffer. I wrecked a set of knives jointing plywood. The knives left neat ridges in a board where they had hit the glue in the ply.

Many of the box stores carry plywood made in China and has been found to have such things as razor blades or other metal in it,it also has been know to de laminate . So no matter what type of joinery you use it may not make a good project.

I’d use the table saw and call it a success…clean up the edge with sandpaper. I just don’t see an application that would require a clean, jointed edge on regular plywood (baltic birch is a different story), at least not at risk of wrecking your jointer blades. If you don’t care much about your jointer plane, then you could use it.

Ok so I tried it anyway as sometimes you just need to see what happens. I was ripping the plywood into 2” strips and then face glueing the faces together for a special effect. Since I needed the edge clean and without saw marks I did 2 passes per board with the jointer and everything was fine. No damage to the blades that I could see after inspection. I also moved the fence several times so that I wasn’t using just one part of the knives.

I’m not sure why, and didn’t even realize it until you asked the question, but I typically grab my dewalt hand planer when I joint plywood. Maybe I knew the above but didn’t know I knew it. I also tend to take very shallow cuts.
